PURPOSE:To obtain mixing water at stable temperature even if a temperature difference is little by heat-exchanging a fluid during flowing in a valve element so that the fluid is conducted to a mixing chamber when a temperature difference becomes little. CONSTITUTION:A lot of small holes 24 are bored in a valve element 20 in such a manner that the opening amount is maximum at the low temperature fluid inlet side and gradually decreased. On the opposite high temperature fluid side, a lot of small holes 24' are bored in such a manner that the opening is fully closed at the start position, and the opening amount is gradually increased with the turning of the valve element 20. The hollow 23 portion of the valve element 20 is partitioned into two passages 23', 23 by a partition plate 25 so that both high-temperature fluid and low-temperature fluid individually flow in from the small holes 24, 24' and flow to the tube shaft 22 side. A lot of outflow small holes 26 from which the fluids flow in the mixing chamber 11 of a valve box through every passage are bored in the peripheral surface of the tube shaft 22 portion. |
